There seems to be little doubt that the Carver mount is the way to go in GSSF competition. And when it comes to red dot sights, the majority of competitors use the C-More or one of the Tasco/BSA (which appear to be the same) or Bushnell units. My question is, while the UltraDot seems to be "the red dot" for Bullseye competition, there is little mention of them in GSSF competition? Conversely, there is little mention of the C-More in Bullseye. Is it the nature of the competitions that favor one sight over another? I have an UltraDot on my MKII and it is great and I was thinking about getting one for my 34 with a Carver mount but don't want to make a mistake putting on the "wrong" sight on if for some reason the C-More is better for GSSF. What's the story?
